Shock Absorber Function

Virtually all manufacturing processes involve movement of some kind. In production machinery this can involve linear transfers, rotary index motions, fast feeds etc. At some point these motions change direction or come to a stop. Any moving object possesses kinetic energy as a result of its motion and if the object changes direction or is brought to rest, the dissipation of this kinetic energy can result in destructive impact forces within the structural and operating parts of the machine.

9

Kinetic energy increases as the square of the speed and the heavier the object, or the faster it travels, the more energy it has. An increase in production rates is only possible by dissipating this kinetic energy smoothly and thereby eliminating destructive deceleration forces. Older methods of energy absorption such as rubber buffers, springs, hydraulic dashpots and cylinder cushions do not provide this required smooth deceleration characteristic – they are non linear and produce high peak forces at some point during their stroke. The optimum solution is achieved by an ACE industrial shock absorber. This utilises a series of metering orifices spaced throughout its stroke length and provides a constant linear deceleration with the lowest possible reaction force in the shortest stopping time.

Stopping Stroke

Energy Capacity

1. Hydraulic Dashpot (High stopping force at start of the stroke). With only one metering orifice the moving load is abruptly slowed down at the start of the stroke. The braking force rises to a very high peak at the start of the stroke (giving high shock loads) and then falls away rapidly. 2. Springs and Rubber Buffers (High stopping forces at end of stroke). At full compression. Also they store energy rather than dissipating it, causing the load to rebound back again. 3. Air Buffers, Pneumatic Cylinder Cushions (High stopping force at end of stroke). Due to the compressibility of air these have a sharply rising force characteristic towards the end of the stroke. The majority of the energy is absorbed near the end of the stroke. 4. ACE Industrial Shock Absorbers (Uniform stopping force through the entire stroke). The moving load is smoothly and gently brought to rest by a constant resisting force throughout the entire shock absorber stroke. The load is decelerated with the lowest possible force in the shortest possible time eliminating damaging force peaks and shock damage to machines and equipment. This is a linear deceleration force stroke curve and is the curve provided by ACE industrial shock absorbers. In addition they considerably reduce noise pollution.

Standard Design of ACE Miniature Shock Absorbers

ACE Design for Higher Demands

These miniature shock absorbers have a static pressure chamber. The dynamic piston forces the hydraulic oil to escape through the metering orifices.

ACE Piston Tube Technology: The increased volume of displaced hydraulic oil provides 200% more energy absorption capacity in comparison with the standard design. The wider effective weight range enables these dampers to cover a much wider range of applications. The piston and inner tube are combined into a single component.

The displaced oil is absorbed by the accumulator. A static seal system containing a U-cup and a wiper seals the shock absorber internally. The outer body and the pressure chamber are fully machined from solid with closed rear end.

ACE Stretch and Rolling Diaphragm System: By the proven dynamic ACE rolling diaphragm seal system the shock absorber becomes hermetically sealed and provides up to 25 million cycles. The rolling diaphragm seal allows direct installation into the end cover of pneumatic cylinders (up to 7 bar). These technologies are used separately or combined on the MC150M to MC600M, SC225M to SC2650M, SCS300 to SCS650 and on the models MC30M-Z and MA150M.

Built-in Safety

12

Industrial shock absorbers and automobile braking systems have two crucial functional similarities: 1. Both should bring a moving mass quickly and safely to rest without any recoil or “bounce back”. 2. Both must never suddenly fail without warning. ACE industrial shock absorbers are built to the highest quality. Shock absorber bodies and inner pressure chambers are fully machined from solid high tensile alloy steel. This gives a completely closed end one-piece pressure chamber with no seals or circlips being necessary. The advantage of this design concept is that the ACE shock absorber is able to withstand much higher internal pressures or overload without damage, giving a very high safety margin. The chance of a sudden failure due to overload etc. is effectively ruled out.

Piston Rod high tensile steel hardened and corrosion resistant.

Bearing maintenance-free, self-lubricating and self-retaining.

Seals only one dynamic seal. Hermetically sealed rolling diaphragm sealing system.

Piston Tube with integral piston check valve and metering orifices. Fully machined from solid with closed rear end to withstand internal pressures up to 1000 bar.

Self-Compensating Industrial Shock Absorbers are maintenance-free, self-contained hydraulic devices with multiple metering orifices which extend through the complete stroke length. After the moving load contacts the shock absorber the piston moves back creating an immediate pressure rise in the pressure chamber. The hydraulic oil behind the piston can initially escape through all the metering orifices. The number of metering orifices in action decreases proportionally to the distance travelled through the stroke. The impact velocity of the moving load is smoothly reduced. The internal pressure and thus the reaction force (Q) remain essentially constant thoughout the complete stroke length providing a constant deceleration rate or: Linear Deceleration

Miniature Shock Absorbers MC150 to MC600 Self-Compensating

20

ACE miniature shock absorbers are maintenance-free, self-contained hydraulic components. The hermetically sealed rolling diaphragm seal system used on the MC150 to MC600 model range provides the highest possible cycle lifetime; up to 25 million cycles being achievable. All models incorporate an integral positive stop. The rolling diaphragm seal provides an extremely low rod return force. These models can be directly mounted into the end cover of pneumatic cylinders (up to 7 bar) to provide superior end damping compared to normal cylinder cushions. By adding the optional side load adaptor it is possible to accept side loads up to 25° from the axis. The wide range of models available ensure a seamless range of operation on applications with effective weights ranging from 0.9 kg up to 4 536 kg by selecting the appropriate model.

Miniature Shock Absorbers SC190 to SC925 Soft-Contact and Self-Compensating

22

ACE miniature shock absorbers are maintenance-free, self-contained hydraulic components. The SC-Series provide dual performance benefits. They provide “soft contact” deceleration where initial impact reaction forces are very low with the advantages of self-compensation to cope with changing input energy conditions without adjustment. They have long stroke lengths to provide smooth deceleration and low reaction forces. They have an integrated mechanical stop and are ideal for use on handling equipment, linear transfers, rodless cylinders and pneumatic pick and place systems etc. The overlapping operating ranges enable the SC series to handle effective weights ranging 0.7 kg up to 2 088 kg. With the optional side load adaptor fitted they can cope with the side loads up to 25°.

Miniature Shock Absorbers SC²-Series Self-Compensating

24

ACE miniature shock absorbers are maintenance-free, self-contained hydraulic components. The design of the SC2-Series units combines the piston and inner tube into a single component and provides more than double the energy capacity of previous units in the same envelope size. They have an integrated mechanical stop and are ideal for use on handling equipment, linear transfers, rodless cylinders and pneumatic pick and place systems etc. The smaller sizes up to type SC2190, have a dynamic membrane seal which allows direct installation into the end cover of pneumatic cylinders (for end position damping max. 7 bar). The greatly increased energy capacity coupled with overlapping effective weight ranges covering from 1 kg up to 6 350 kg makes the SC2-Series units ideal for rotary actuators. With the optional side load adaptor fitted they can cope with the side loads up to 25 °.

“Combined piston and inner tube – increased energy capacity up to 200%!”

Miniature Shock Absorbers MA Adjustable

26

ACE miniature shock absorbers are maintenance-free, self-contained hydraulic components. If you prefer a fully adjustable shock absorber rather than a self-compensating model on your application then the MA series provide a directly interchangeable alternative. The adjustable series include an integrated mechanical stop. These adjustable units have long stroke lengths (MA925 with 40 mm superstroke) to provide smooth deceleration and low reaction forces. The MA150 incorporates the proven rolling diaphragm seal (used on the MC150 to MC600 range) and shares all the advantages of that technology. The stepless adjustment range of the MA series covers an effective weight range from 0.2 kg up to 2 040 kg.

Air Bleed Collar (includes integral stop collar) protects shock absorber from ingress of abrasive contaminents like cement, paper or wood dust into the rod seal area. It also prevents aggressive fluids such as cutting oils, coolants etc. damaging the seals. Air bleed supply 0.5 to 1 bar. Low air consumption. The constant air bleed prevents contaminants passing the wiper ring and entering the shock absorber seal area. Note! Do not switch off air supply whilst machine is operating! The air bleed collar can not be used on all similar body thread sized shock absorbers. The air bleed collar is only for types MC150M to MC600M, MA150M, SC²75 and SC²190M5-7.

Grinding beads, sand, welding splatter, paints and adhesives etc. can adhere to the piston rod. They then damage the rod seals and the shock absorber quickly fails. In many cases the installation of the optional steel shroud can provide worthwhile protection and increase lifetime. Note! When installing don’t forget to allow operating space for the shroud to move as the shock absorber is cycled. For part number MA, MC, SC please order with “M-880” suffix. Part numbers MA150M, MC150M to MC600M and SC²25M to SC²190M5-7 are supplied without a button, for advice on removing the button see page 34.

Side Load Adaptor

With side load impact angles of more than 3° the operation lifetime of the shock absorber reduces rapidly due to increased wear of the rod bearings. The optional BV side load adaptor provides long lasting solution. Secure the side load adaptor with Loctite or locknut on the shock absorber. Material: Threaded body and plunger: Hardened high tensile steel. Hardened 610 HV1. Note: For material combination plunger/impact plate use similar hardness values. We recommend that you install the shock absorber/side load adaptor using the thread on the side load adaptor.

Threaded Body

Note! Installation with clamp mount MB... not possible. Use mounting block MB... SC².

Plunger

Problem: Rotating impact motion causes high side load forces on the piston rod. This increases bearing wear and possibly results in rod breakage or bending. Solution: Install side load adaptor BV. Rs

Formulae: α = tan-1

( Rss )

Example: s = 0.025 m Stroke s Hub s α

α max = 25° (Type BV25)

Rs = 0.1 m α = tan-1

( 0.025 0.1 )

α = 14.04°

Rsmin = 0.054 m

α max s

= max. angle ° Rsmin = min. possible = absorber stroke m mounting radius m

Rs

= mounting radius m

Note: By repositioning the centre of the stroke of the side load plunger to be at 90 degrees to the piston rod, the side load angle can be halved. The use of an external positive stop due to high forces encountered is required. Note! The BV adaptor can only be installed onto a shock absorber without rod end button. Part Number: MA, MC, SC...-880 (Models MA150M, MC150M to MC600M and SC²25M to SC²190M5-7 are supplied as standard without buttons.) To remove button from existing absorber: Clamp shock absorber in mounting block and warm button carefully. Grip the button with pliers and pull off along rod axis. Time required for warming up the button: up to M12x1: approx. 10 sec. from M14x1.5 up: approx. 30 sec.

PP...

While the use of industrial shock absorbers already achieves a considerable reduction in noise levels, the additional use of PP impact buttons made of glass fibre reinforced nylon reduces noise levels even further, making it easy to fulfil the regulations of the new Noise Control Ordinance. At the same time, wear of impact surface is drastically minimized. The PP buttons are available for shock absorbers in series MC150M to MC600M. They are fitted simply by pressing onto the piston rod.

These new impact buttons made of urethane offer all above advantages of the PP nylon button in terms of reducing noise and wear. They fit easily onto the piston rod of the corresponding shock absorber. The head is then secured by a circlip integrated in the drilled hole of the steel base material.

With all other models you must order the PS button as an optional accessory. Mounting: We recommend to fix the steel button onto the end of the piston rod using Loctite 290. Attention! Take care not to leave any adhesive on the piston rod as this will cause seal damage. Thread the switch stop collar onto the front of the shock absorber and secure in position.

Industrial Shock Absorbers MA and ML33 to 64 Adjustable

This adjustable shock absorber from ACE is unique. The innovative MAGNUM series models provide the next generation of deceleration technology to meet the needs of the future. The latest seal technology, a hardened main bearing and the integrated positive stop provide a significant increase in operating lifetime. Other innovations such as the front and rear adjuster, new clamping flanges and the fully threaded outer body provide many new options in installation and mounting. Exploit the advantages of this series in your applications with its 50 % increased energy capacity and a much wider effective weight range. The effective weight range extends from 9 kg up to 80 000 kg. The MA range models cover the majority of standard applications, whilst the ML range is specially designed for low velocity/high effective weight applications from 300 kg up to 500 000 kg effective weight.

Grinding beads, sand, welding splatter, paints and adhesives etc. can adhere to the piston rod. They then damage the rod seals and the shock absorber quickly fails. In many cases the installation of the optional steel shroud can provide worthwhile protection and increase lifetime. Material: Hardened high tensile steel. Mounting: To mount the PB steel shroud it is necessary to remove the rod end button of the shock absorber. Note! When installing don’t forget to allow operating space for the shroud to move as the shock absorber is cycled.

Mounting Hints and Operation Details

48

Mechanical Stop The MAGNUM Series units have a built in stop collar (mechanical stop) which also serves as the front adjuster. If using a shock absorber without a stop collar it is important to install a mechanical stop 0.5 to 1mm before the end of the stroke.

MA and ML only

General

Adjustable Models

For optimum heat dissipation do not paint the shock absorber. For applications in environments with acids, dusts or powders, abrasives, steam or water please protect the shock absorber and/or consider the special accessories on page 45. The shock absorber should be securely mounted onto a flat and smooth surface of adequate strength.

The adjustment has a graduated scale from 0 to 9. The adjuster in the body of MA/ML64 has a side mounted locking screw which should be loosened (1/2 turn max.) with a hex. key before commencing adjustment. The MAGNUM Series units can be adjusted by the hex. socket at the rear of the body or by rotating the front stop collar. Both adjusters are internally connected and will show the same adjustment value on the scales as they are turned. After installation cycle the equipment a few times and turn the adjustment until optimum deceleration is achieved (i.e. no abrupt change in the load velocity observed at the beginning or at the end of shock absorber stroke). The shock absorber is delivered set at 5.

Self Compensating Models The MC family of shock absorbers are self compensating. Providing the effective weight on the application remains within the band given in the capacity charts then no adjustment is necessary for changes in weights, speeds or propelling force. These units are available with five standard operating bands (me min. – me max.) and are identified by the suffix number after the model which goes from -0 (very soft) up to -4 (very hard). The optimum deceleration is achieved when there is no abrupt change in the load velocity at the beginning or the end of the shock absorber stroke. If there is a hard impact at the start of stroke use the next softer version (i.e. lower suffix number). If there is a hard setdown at the end of stroke use the next harder version, or mount two units in parallel.

If there is a hard impact at start of stroke adjust the unit softer i.e. towards 9 on the scale. If there is a hard setdown at end of stroke adjust the unit harder i.e. towards 0. Adjustment approaching “0” means: a) Impact velocity is too low: consider changing to Model type ML or: b) Shock absorber selected is too small: use next larger size or mount 2 units in parallel.

Alternatively change to a larger bore size unit. Contact ACE for further advice.

Repairs It is possible to overhaul ACE shock absorbers in M33 sizes and larger. We would recommend that damaged or worn shock absorbers are returned to ACE for repair. You will find

48

that this is more economic than the comparative cost of repairing yourself. Spare parts and seal kits etc. are available however if required.

The CA2 to CA4 complete the ACE product range of self-compensating shock absorbers. With these units ACE has a continous range of self-compensating units to handle effective weights from 0.3 kg up to 326 000 kg. The robust CA series units are designed for really heavy duty applications. Damage caused by errors in adjustment setting is ruled out by their self-compensating design. You can select the correct model for your application using the ACE Selection Program or by using the capacity chart. In comparison with the earlier SAHS range the CA 2" has 70 % and the new CA 3" 25 % higher capacity. The CA units are maintenance-free and available self-contained or for use with an external air/oil tank.

1 ACE Shock absorbers for pneumatic cylinders

With heavy loads or high velocities normal cylinder cushions are often overloaded. This causes shock loading leading to premature cylinder failure or excessive maintenance. Using oversized cylinders to withstand this shock loading is not the best solution since this considerably increases air consumption and costs.

For: optimum deceleration higher speeds smaller cylinders reduced air consumption smaller valves and pipework Example: MA3350-Z (cylinder mounting)

Seal with Teflon tape or sealant

2 Side load adaptor for high side load angles Rs

The side loading is removed from the shock absorber piston rod leading to considerably longer life. See pages 34 and 45 for more details.

3 Undamped free travel with damped end position

Free travel

The lever 1 swings with the pin 2 in a slotted hole around pivot point 3. The lever is smoothly decelerated at the extreme end of its travel.

2 1

4 One shock absorber for both ends of travel

It is possible to use only one shock absorber for both end positions by using different pivot points as shown.

Pivot point of lever

Shock absorber stroke

5 Double acting shock absorber

With a little additional work a normal unidirectional shock absorber can be converted to work in 2 directions by using a mechanism as shown.

6 Air bleed collar

By using the air bleed adaptor the operating lifetime of shock absorbers in aggressive environments can be considerably increased. The adaptor protects the shock absorber seals from cutting fluids, cleaning agents, cooking oil etc. by using a low pressure air bleed. For more details see page 33.

7 Double stroke length

50 % lower reaction force (Q) 50 % lower deceleration (a) By driving 2 shock absorbers against one another ‘nose-to-nose’, the effective stroke length can be doubled.

8.1 The latch absorbs the kinetic energy so that the object contacts the fixed stop gently.

8.2

Issue 4.2009 Specifications subject to change

8.2 The latch absorbs the rotational energy of the turntable etc. The turntable can then be held in the datum position with a lock bolt or similar.

9 Rotary actuator or rack and pinion drive

The use of ACE shock absorbers allows higher operating speeds and weights as well as protecting the drive mechanism and housing from shock loads.

10 Adjustable stop clamp e.g. for handling equipment

The gentle deceleration of ACE shock absorbers makes the use of adjustable stop clamps possible and removes any chance of the clamp slipping. The kinetic energy is completely removed before the mechanical stop is reached thus making high index speeds possible.

11 Ride-over latch e.g. fire door

The fire door travels quickly until it reaches the lever. It is then gently decelerated by the lever mounted shock absorber and closes without shock or danger to personnel.

Door Safety travel (prevents tapping)

12 Increasing stroke length mechanically

By means of a lever the effective stroke length can be increased and mounting space to the left reduced.

Miniature Shock Absorbers Application Examples

58

ACE miniature shock absorbers are the right alternative. This pneumatic module for high precision, high speed motion intentionally abandoned pneumatic end-oftravel damping. The compact miniature shock absorbers of the type MC25MH-NB decelerate the linear motion safer and faster when reaching the end-oftravel position. They accept the moving load gently and decelerate it smoothly throughout the entire stroke length. Additional advantages: simpler construction, smaller pneumatic valves, lower maintenance costs as well as reduced compressed air consumption.

Constant resisting force

Rs

Stroke

The cycle rate for an assembly line producing electronic components was increased to 3600 units/hr by using ACE shock absorbers. Miniature shock absorbers type SC190M-1 decelerate the rapid transfer movements on the production line and using soft damping methods optimise the pick up and set down of components. This soft deceleration technique has increased production and reduced maintenance on the portal and rotary actuator modules. The optional side load adaptor protects the shock absorber from high side load forces and increases the operating lifetime. Using ACE shock absorbers reduces maintenance costs by 50% and running costs by 20%, diminishing energy consumption.

Industrial Shock Absorbers Application Examples

ACE industrial shock absorbers offer safety to spare for swiveling or braking of large telescope. The optical system ot this telescope for special observations is moveable in two space coordinates. The structure in which the telescope is mounted weighs 15000 kg and consists of a turntable with drives and two wheel disks rotating on bearings. It enables a rotation by ± 90° from horizon to horizon. To safeguard the telescope in case of overshooting the respective swiveling limits, industrial shock absorbers of the type ML3325M are used as braking elements. Should the telescope inadvertently overshoot the permissible swivel range, they will safely damp the travel of the valuable telescope.

This device driven by piston rod-less pneumatic cylinders, in which two gripper slides are moving independently of each other at speeds of 2 to 2.5 m/sec., is equipped with industrial shock absorbers as brake systems. Their function is to stop a mass of 25 kg up to 540 times per hour. The model MC3350M-1-S was chosen for this application, allowing easy and extremely accurate adjustment of the end positions of the adjustable limit stops. In comparison to brake systems with other function principles, shock absorbers allow higher travel speeds and shorter cycle sequences.
